Kallang-Paya Lebar Expressway (KPE)

What is the KPE?

Opened to traffic on 20 September 2008, the 12 km Kallang-Paya Lebar Expressway (KPE) is Singapore’s ninth expressway. Costing S$1.7 billion to build, it includes:

9 km of cut-and-cover underground tunnels

6 traffic lanes

8 interchanges and 6 ventilation buildings

With 75% of the expressway underground, we introduced several measures to ensure road safety for drivers:

A KPE Operations Control Centre monitors the traffic 24 hours a day leveraging on various systems like automatic incident-detection cameras that pick up unusual situations, e.g. stopped vehicle along main carriageway

State-of-the-art fibre-optic heat detectors to detect fire and air monitoring sensors to monitor tunnel air temperature and carbon monoxide levels, and activate fire alarms and tunnel ventilation system, if necessary.

A speed limit of 70 km/hour to lower the risk of accidents in the tunnels.

Where is the KPE?

The KPE starts from East Coast Parkway (ECP) in the south, crossing under the Geylang River, Nicoll Highway, Mountbatten Road, Geylang Road, Sims Avenue and the Pan Island Expressway (PIE).

The route continues from Aljunied Road and Upper Paya Lebar/Paya Lebar Road before following Airport Road past the Paya Lebar Air Base to connect to Tampines Expressway (TPE) in the north-east.
